If you want to see possibly the only extant Bb soprano rothophone, head down to YouTube (at about 2:14). (I think it's actually a saxoboe.)
Helen's article on an alto rothophone (lots of pics!) And another alto The baritone rothophone.
If you want to change how many album pictures per page, use CTRL+ and CTRL- (Command + and Command - if you have a Mac). 80% looks great on my 4K monitor.
